Posterior capsular rupture (PCR) is an infrequent complication of cataract surgery that can lead to significant ocular morbidity and permanent vision loss. In the setting of PCR, the primary objective is the safe and thorough evacuation of vitreous and lens fragments from the anterior segment. The secondary objective is the stable placement of an intraocular lens (IOL) selected for best refractive outcomes. Expedited referral to vitreoretinal specialists is recommended for management of posteriorly dislocated lens material and surveillance for retinal injury. It is the intention of this review to present current guidelines for the management of PCR.
There are new techniques available to anterior and posterior segment surgeons in the setting of PCR. Endoillumination may facilitate visualization during anterior vitrectomy and the IOL may be used as a pupillary barrier to prevent loss of lens fragments. When secondary procedures are needed, early return to the operating room and small-gauge pars plana techniques may reduce patient morbidity.
When approached carefully and systematically, patients may have good outcomes in the setting of PCR. Recent advancements in instrumentation and technique encourage further study and may lead to new standards of care.
后囊破裂(PCR)是白内障手术的一种罕见并发症,可导致严重的眼部发病率和永久性视力丧失。在 PCR 的情况下,主要目标是安全、彻底地从前节清除玻璃体和晶状体碎片。次要目标是稳定地放置选择用于最佳屈光效果的人工晶状体(IOL)。建议尽快向玻璃体视网膜专家转诊,以管理后脱位的晶状体材料并监测视网膜损伤。本综述旨在介绍目前针对 PCR 管理的指南。
在 PCR 的情况下,前节和后节外科医生有新的技术可用。内照明术可在前段玻璃体切除术中提供可视化,并且 IOL 可用作瞳孔屏障以防止晶状体碎片丢失。当需要进行二次手术时,早期返回手术室和小口径巩膜切除术技术可能会降低患者的发病率。
当谨慎且系统地处理时,患者在 PCR 的情况下可能会有良好的结果。仪器和技术的最新进展鼓励进一步研究,并可能导致新的护理标准。
